1.  Damage control surgery in patient with delayed rupture of pseudoaneurysm after blunt abdominal trauma 
Delayed rupture of post-traumatic pseudoaneurysms of the visceral arteries, especially the pancreaticoduodenal artery, is uncommon. Here, we describe a 55-year-old man hemorrhaging from a pseudoaneurysm of the inferior pancreaticoduodenal artery (IPDA). Computed tomography of the abdomen showed active bleeding in the IPDA and large amounts of hemoperitoneum and hemoretroperitoneum. Selective mesenteric angiography showed that the pseudoaneurysm arose from the IPDA, and treatment by angioembolization failed because the involved artery was too tortuous to fit with a catheter. Damage control surgery with surgical ligation and pad packing was successfully performed. The patient had an uncomplicated postoperative course and was discharged 19 days after the operation. To our knowledge, this is the first report of ruptured pseudoaneurysm of an IPDA after blunt abdominal trauma from Korea.

2.  Primary leiomyosarcoma of the pancreas 
Journal of the Korean Surgical Society  2011;81(Suppl 1):S69-S73.
Primary sarcomas of the pancreas are extremely rare, accounting for 0.1% of malignant pancreatic (non-islet) neoplasms. Pancreatic leiomyosarcoma is a highly aggressive malignancy that spreads in a similar manner to gastric leiomyosarcoma, i.e., by adjacent organ invasion, hematogenous spread, and lymph node metastasis. These tumors are large at the time of diagnosis and are usually found at an advanced stage. We report a case of a 70-year-old female with intermittent right upper quadrant abdominal discomfort. Radiological, histopathological, and immunohistochemical studies revealed the tumor to be a primary leiomyosarcoma of the pancreas. Herein, we describe a patient with a primary leiomyosarcoma of the pancreas who presented with clinical and radiological findings indicative of a mass in the pancreatic head.

3.  Inguinal hernia repair in overweight and obese patients 
To describe the clinical characteristics and outcomes after inguinal hernia repair in overweight and obese patients.
We retrospectively reviewed the medical records of 636 adult patients who underwent mesh plug inguinal hernia repair performed by one surgeon from November 2001 to January 2009.The clinical characteristics and surgical outcomes of the patients were analyzed. According to the body mass index, patients higher than 23 were defined as overweight and obese patient group (O group) and patients between 18.5 and 23 were defined as normal weight patient group (N group). Seventeen underweight patients were excluded in this study.
Of 619 cases, the number for O group was 344 (55.6%) and for N group was 275 (44.4%). The mean age was significantly higher in N group (62.2 ± 12.6 vs. 64.4 ± 14.8, P = 0.048). Underlying diseases were present in 226 (65.7%) of the O group and 191 (69.5%) of the N group (P = 0.322). Anesthesia method, operative time and postoperative hospital stay had no significant difference between the two groups. Postoperative complications developed in 41 (11.9%) of the O group and in 28 (10.2%) of the N group, respectively, and no major complications developed in either group.
Adult inguinal hernias developed at a relatively younger age in overweight and obese patients than in normal weight patients. There were no specific differences in other clinical characteristics and outcomes between the two groups. Therefore inguinal hernia repair in overweight and obese patients is a safe procedure as in normal weight patients.

4.  Undifferentiated carcinoma of the pancreas with osteoclast-like giant cells 
Undifferentiated carcinoma with osteoclast-like giant cells is a rare neoplasm of the exocrine pancreas. Some similar cases have been reported, but the histogenesis of these tumors varies and is controversial. We report here on a case of undifferentiated carcinoma of the pancreas with osteoclast-like giant cells. A 77-year old woman presented with abdominal pain and anorexia. Abdominal computed tomography and magnetic resonance imaging showed an approximately 10 × 5 cm highly attenuated mass arising from the tail of the pancreas and invading the spleen and adjacent bowel loop. The initial impression was a malignant endocrine tumor or solid-pseudopapillary tumor of the pancreas. The patient underwent a distal pancreatectomy with splenectomy and left hemicolectomy. The histopathology and immunohistochemistry helped make the diagnosis that of an undifferentiated carcinoma with osteoclast-like giant cells of the pancreas.

5.  Inguinal hernia repair in patients with liver cirrhosis accompanied by ascites 
We describe the clinical characteristics and assess the outcomes and stability of inguinal hernia repair under local anesthesia for patients with liver cirrhosis accompanied by ascites.
We retrospectively reviewed the medical records of 22 patients with cirrhosis and ascites who underwent mesh plug hernia repair performed by a single surgeon from January 2002 to August 2009, and the clinical characteristics and outcomes of the patients were analyzed.
Twenty-two patients were included in the study. Fifteen (68.2%) were Child's class B and seven (31.8%) were Child's class C. Hernia repairs were successful without major complications or recurrence in all patients. Minor complications occurred in only three patients, consisting of two hematomas and one case of scrotal swelling. Complications were resolved spontaneously without the need for blood transfusion or reintervention. Thirteen patients died during follow-up (59.1%); eight of these patients died within 1 year after hernia repair. However, there was no 30-day postoperative mortality. Five of the eight patients who died were Child's class B and the remaining three patients were Child's class C. Deaths were all related to cirrhotic complications, and there was no operation-related mortality.
Inguinal hernia repairs under local anesthesia in patients with cirrhosis accompanied by ascites were performed safely and effectively. Therefore, surgical repair is recommended even in patients with refractory ascites and poor hepatic function to prevent life-threatening complications or severe pain and improve quality of life.

6.  Liver resection for hepatocellular carcinoma: case-matched analysis of laparoscopic versus open resection 
To analyze the outcomes of laparoscopic liver resection compared with open liver resection in patients with hepatocellular carcinoma (HCC).
Between July 2005 and December 2009, 26 consecutive patients with HCC underwent a pure laparoscopic liver resection, and data from this group (laparoscopic liver resection group, L-group) were compared with a retrospective control group of 29 patients who underwent open liver resection for HCC (open liver resection group, O-group) during the same period. The two groups were matched in terms of demographic data, tumor size, degree of liver cirrhosis, American Society of Anesthesiology score, type of resection, and tumor location.
Median operation time and the amount of intraoperative packed red blood cell transfusion in the L-group were 147.5 minutes and 0.35 units, respectively. The L-group revealed a shorter operation time (147.5 vs. 220.0 minutes, P = 0.031) than the O-group. No difference in perioperative morbidity or mortality rates was observed (3.8, 0 vs. 24.1%, 0%; P = 0.054, non-specific, respectively); the L-group was associated with a shorter hospital stay than the O-group (11.08 vs. 16.07 days, P = 0.034). After a mean follow-up of 23.9 months (range, 0.7 to 59.4 months), the 1-year disease-free survival rate was 84.6% in the L-group and 82.8% in the O-group (P = 0.673).
Laparoscopic liver resection for HCC is feasible and safe in selected patients and can produce good surgical results with a shorter postoperative hospital stay and similar outcomes in terms of perioperative morbidity, mortality, and disease-free survival than open resection.

7.  Cystic lymphangioma of the pancreas mimicking pancreatic pseudocyst 
Journal of the Korean Surgical Society  2011;80(Suppl 1):S55-S58.
Lymphangiomas are rare congenital benign tumors arising from the lymphatic system, and are mostly encountered in the neck and axillary regions of pediatric patients (95%). Lymphangioma of the pancreas is extremely rare accounting for less than 1% of these tumors. We report here on a case of pancreatic cystic lymphangioma. A 54-year-old woman presented with intermittent postprandial abdominal discomfort and radiating back pain. Abdominal computed tomography scan revealed 8 × 6.5 cm hypodense cystic mass arising from the tail of the pancreas without septa or solid component. The initial impression was a pancreatic pseudocyst. The patient underwent distal pancreatectomy with splenectomy. The histopathologic and immunohistochemical study helped make the diagnosis of a pancreatic cystic lymphangioma. Herein, we report a case of pancreatic cystic lymphangioma mimicking pancreatic pseudocyst and review the relevant medical literature.
